The Quantum Astrophysicists Guild

The Quantum Astrophysicists Guild was created in 2011 by Ty Taylor. Ty, along with artist Mario Castaneda, released QAG's first game, The Bridge, in 2013. The Bridge, a black-and-white M. C. Escher inspired puzzler, has been featured in numerous game competitions and festivals around the world. During The Bridge's development, it was one of the PAX 10 selected games, in addition to receiving the Best Gameplay and Best Art awards at the Indie Game Challenge and being featured in the IGF, IndieCade, Dream.Build.Play, A.MAZE, and various other international game competitions. After QAG released The Bridge on Steam and Xbox Live Arcade, the game received tremendous critical reception, and it has sold over 500,000 copies to date. Now Ty and Mario, with the new additions of Alex Schearer and Justin Nafziger, are working on a new project: Tumblestone, a fast-paced multiplayer game with maddeningly addictive gameplay. Tumblestone hit the shelves July 12th 2016.
